Unfortunately, the detailed underhood vehicle specification sticker is gone, but the VIN on the door tag reads: D14BD6S327675. D1 = D100 1/2-ton, two-wheel-drive pickup, 4 = Sweptline conventional cab and bed, B = 6,001 to 10,000 GVW, D = 440ci V-8, S = Warren, Michigan, plant No. 1, 327675 = production sequence. What we really care about is that D in the fifth position. More common engine offerings were the 225 Slant Six one-barrel (B-code), 225 Slant Six two-barrel (C-code), 318 (E-code), 360 (F- code), and low-deck 400 big-block (H-code).
